The strategy for configuring the Win7 system firewall

The firewall was introduced by Microsoft in the XP system, and has since steadily improved the firewall function. It is a revolutionary improvement in the Win7 system, providing us with more powerful features. Therefore, we will introduce Windows Firewall in Windows 7, and how to configure issues with multiple firewall policies.

History of Windows Firewall

The firewall software in Windows XP provides only simple and basic functions, and only protects inbound traffic, blocking any inbound connections that are not natively started. Default In the case, the firewall is turned off. The SP2 system is enabled by default, allowing system administrators to enable firewall software through Group Policy. Vista's firewall is built on the new Windows Filtering Platform (WFP), which adds the ability to filter outbound traffic through the Advanced Security MMC snap-in. In Windows 7, Microsoft has further tuned the firewall's capabilities to make the firewall more user-friendly, especially on mobile computers, and capable of supporting multiple firewall policies.

Windows7 Firewall

In Vista, the basic settings of the Windows 7 firewall are set through the control panel program. Unlike Vista, you can also access advanced settings (including configuration via the control panel). Station connection filtering) without creating an empty MMC and adding a snap-in. Just click on the advanced settings link in the left panel.

More Network Options

Vista Firewall allows users to choose public or private networks. In Windows 7, you have three choices: public network, home network or working network, both of which are It is considered a private network.

If you choose the "Home Network" option, you can create a Homegroup. In this case, network discovery (networkdiscovery) is automatically turned on so that you can see other computers and devices on the network, and they can see your computer. Computers belonging to Homegroup can share pictures, music, videos, and document libraries, as well as share hardware devices such as printers. If you have files in your folder that you don't want to share, you can also exclude them.

If you choose "Work Network", the network discovery is enabled by default, but you will not be able to create or join Homegroup if you add your computer to the Windows domain (via ControlPanel| System| AdvancedSystemSettings| ComputerNametab) and through domain controller verification, the firewall will automatically treat the network as a domain network.

When you connect to a public wireless network or use a mobile broadband network at airports, hotels or cafes, you should choose "public network"; network discovery will be off by default, so that in the network Other computers can't see your computer, you can't play Sichuan opera or belong to Homegroup.

For all network types, by default, Windows 7 Firewall blocks connections to programs that are not on the Allowables list. Windows 7 allows you to configure settings for each type of network. The above is the strategy of firewall configuration in Win7 system that we share for you. I hope everyone can help.
